Work Zone Safety and Innovative Pavement Technologies at Top of NAPA’s 2022 Focus Areas

Federal law requires federal agencies, including the U.S. Department of Transportation, to revise and update their strategic plan at the beginning of each new presidential term.  In so doing, the DOT invited stakeholders to comment on the Draft DOT Strategic Framework, which included draft strategic goals and strategic objectives to accomplish each strategic goal.

The draft DOT Strategic Framework reflects the agency’s priorities for achieving DOT’s mission through six strategic goals: safety, economic strength and global competitiveness, equity, climate and sustainability, transformation, and organizational excellence. The NAPA organization was the only association providing comments on behalf of the asphalt pavement industry.

NAPA President and CEO Audrey Copeland asked DOT to prioritize worker safety in work zones and the deployment of innovative pavement technologies, both of which should be added to the DOT Strategic Framework. Copeland also recommended the inclusion of a goal: the development of revenue options for the Highway Trust Fund.

Asphalt Materials is Focused on Building, Longer-Lasting, Safer Roads

The Department of Transportation (DOT) published their draft Strategic Framework FY2022-2026, for public comment in November 2021. Shown below are a few of the important elements of the DOT’s document where the focus of Asphalt Materials and this framework as particularly aligned.

A particularly excellent example of a Heritage Group, Heritage Research Lab and Asphalt Materials discovery is VRAM, a void reducing asphalt membrane which has been shown to create longer-lasting safer roads. Many of the objectives, goals and strategies outlined by the DOT can be achieved by using more VRAM across a variety of projects in the United States in 2022 and beyond.

  • VRAM helps build longer-lasting roads lead to a more resilient and reliable infrastructure and supply chain
  • VRAM helps build longer-lasting roads that are more environmentally friendly than many other mechanical methods
  • VRAM helps build longer-lasting roads that are more sustainable
  • VRAM is a breakthrough discovery that helps roads last up to 5 years longer and delivers a return on investment of 3 to 5 times its cost
  • VRAM is a breakthrough innovation that has an impressive track record that has been performing and delivering results since 2002
  • VRAM is being used in 21 states and The District of Columbia. These states can collaborate with other states to accelerate the adoption of the VRAM innovative technology
  • VRAM provides long-term benefits as shown in an Indiana DOT life cycle analysis where an investment of $12.5M in J-Band can result in a $39M in savings (approximately 3:1 ROI).

Asphalt Materials, Inc. an Important Company Within The Heritage Group

At The Heritage Group, we have been developing environmentally sustainable solutions for more than 50 years. We started Heritage Environmental Services with a Subtitle C landfill in 1970, the same year the EPA was created. Today, Heritage Environmental Services is a leader in environmental sustainability and a one-stop waste management solution spread across North America.

Sustainability is important all across The Heritage Group. Our businesses are focused on leaving the world a better place for future generations.

At Asphalt Materials (AMI), we work closely with The National Asphalt Pavement Association (NAPA). NAPA works to support, advocate, and advance the asphalt pavement industry. One of NAPA’s focus areas for 2022 is climate stewardship and how asphalt is environmentally friendly as it is America’s most recycled material. Our industry continuously explores methods and practices to contribute to a sustainable infrastructure and a healthy environment for generations to come.

It is always worth noting that asphalt delivers sustainability by being the most recycled material in the world !

NAPA Helps Answer: What is the Environmental Impact of Asphalt?

The asphalt industry has a long history of working with federal regulatory agencies, including the Environmental Protection Agency (EPA) and OSHA. Since the early 1990s, the EPA has done extensive testing on asphalt plant emissions and in 2002 removed this industrial sector from the “major source” category, identifying that emissions from asphalt plants are not an area of concern. (1) NAPA is the National Asphalt Pavement Association.

Understanding Reclaimed Asphalt Pavement (RAP) as a Clean Fill Material

In 2019, more than 97 million tons of RAP and 921,000 tons of reclaimed asphalt shingles (RAS) were used in new asphalt pavement mixes in the U.S. That year about 139 million tons of RAP and RAS were stockpiled for future use across the country. Reusing RAP in future pavements saved nearly 60 million cubic yards of landfill space during 2019.  (2)

As America’s biggest recycler, millions of tons of asphalt pavement material is reclaimed each year during road widening and resurfacing projects, and nearly all of that material is reused. Incorporating reclaimed asphalt pavement (RAP) into new pavements reduces demands for virgin asphalt binder, helping to keep costs down as well as improving the environmental footprint of projects.

Not all RAP is recycled into new asphalt pavements, however. Occasionally, the question arises as to whether or not RAP can be used as “clean fill.” Although obviously not the highest and best use of this vital resource, regulations regarding when and where RAP can be placed as fill material vary from state to state and can be complex. In most instances, RAP falls under state solid-waste requirements and purview.

Material that is Recycled is Not Considered Solid Waste

Because state environmental agencies often have more restrictive solid-waste disposal regulations than the federal Environmental Protection Agency, it is important to understand how RAP is defined. U.S. EPA classifies RAP as construction and demolition (C&D) debris that is part of the federal solid-waste chain. Federal regulations also identify that if materials are “recycled,” then they are not considered solid waste. However, there is a “speculative accumulation” federal definition that requires a 75 percent annual “turnover” to maintain the recycled material classification vs. solid waste.

There are NO Harmful Compounds Leached from RAP

RAP is not, and never has been, considered a “hazardous” solid waste. Years of leaching studies show that there are no harmful components leached from RAP under the most stringent waste definition extraction conditions. (See NAPA Special Report 190: “Reclaimed Asphalt Pavement (RAP) Stockpile Emissions and Leachate.”) In general, it is acceptable for RAP to be used as a road material — as part of the base, recycled back into pavement, etc. — both from a federal and state perspective. Although U.S. EPA does not appear to have a strict definition of “clean fill”, specific requirements do apply to solid-waste materials applied to land.

The bottom line is that each state’s environmental agency will likely dictate whether or not RAP can be used as a clean fill material. Under normal use and circumstances, RAP should never be considered as hazardous waste. (3)
